I’ve been researching the Nintendo DS hardware, and I came across its Ram. It says it has 4MB of PS Ram. After looking it up online, I can’t really find any simple answers as to what it is? Is it specially designed Ram for the DS? If so, what makes it different?
In: Technology
It’s pseudostatic RAM.
It’s DRAM with a self refresh circuit.
DRAM is more cost effective by density so Nintendo saves some money by using DRAM with the self refresh circuit without sacrificing too much performance by simulating static RAM with the refresh circuit.
